Annotation
Modified derivatives of polysaccharides containing aldehyde groups in their structure are unique intermediate materials for the production of new polymeric compounds. In the present study, periodate oxidation of inulin was carried out. The physicochemical properties of the resulting dialdehyde inulin with varying degrees of oxidation were investigated. Due to the presence of aldehyde groups in the structure of oxidized inulin, immobilization of hydrazine, ethylenediamine, and propylenediamine was performed via covalent azomethine bonds. The presence of diamines in the dialdehyde inulin structure was confirmed by elemental analysis (by nitrogen content) and FTIR-spectroscopy.
